IPC: H04M15/06
Filed: 1961-03-17
Abstract: 949,690. Automatic exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 16, 1962 [March 17, 1961], No. 9864/61. Addition to 869,373. Heading H4K. Metering pulses are distinguished from spurious pulses by determining whether they last for a first predetermined period of time without being interrupted for more than a second predetermined period of time, this being achieved by sampling all pulses at intervals less than either predetermined period and employing a pattern register to record the result of each sample so that a characteristic setting is produced only when the conditions are satisfied. The fastest acceptable incidence of meter pulses is determined by a waveform TWT which controls the addition of a metering pulse to a subscriber's register. A meter pulse is illustrated with scanning intervals at which sampling takes place masked below it as intervals 1 to 13, x and y. A register with bi-stable elements TA1 to TA5 is used to record the results of sampling. The normal state of the register is with O's in all five positions and when meter potential is encountered 1's are written successively, first in positions 1 and 2 and then in turn in positions 3, 5 and 4. Absence of metering potential causes the writing of 0's successively in positions 2, 1 and 3, and if these operations occur in this sequence in response to continuous metering potential present and metering potential absent a metering pulse condition is established with 1's in positions 4 and 5 only. Mutilations do not disturb this conclusion provided that metering potential persists for at least four scans with interruptions of not more than two scans. Collection of an established pulse in a scanning period x is made by a TWT pulse first occurring after establishment with no intervening metering potential detected. On collection the position 5 is reverted to a 0, but position 4 holds its 1 until the scanning period y in coincidence with the TWT pulse next following collection in order to provide a guard period during which no valid metering pulse could occur and in which scanning is consequently ignored. Logic circuitry governing the register positions on a magnetic drum track is described with reference to Fig. 2, not shown.

Title: Improvements in or relating to closure devices for openings in containers
IPC: F01P11/02
Filed: 1945-04-19
Abstract: 593,502. Stoppers. BRISTOL TRAMWAYS & CARRIAGE CO., Ltd., and MORGAN, W. L. April 19, 1945, No. 9885. [Class 125 (iii)] A closure device, especially a filler cap for a motor vehicle radiator, fuel tank or oil filling orifice, comprises a cover part having a sealing plate articulately mounted thereon and adapted to engage a seating around the opening, there being an anchorage between the container and the cover part which permits the latter to move towards and away from the plane of the seating, and constrains it to swing about an axis disposed to one side of the opening and transverse to the plane thereof, means being provided for urging the cover part towards said plane so as to bring the sealing plate into engagement with the seating. In the form shown in Fig. 1 a sealing plate 13 carried by the cap 14 seats on a rib 12 surrounding the orifice 10. The cap 14 is anchored to a platform 17 extending from the body 11 of the filler member by means of a pin 18, which carries a part-spherical bush 21 engaging a conical seating 20, thus providing a limited universal movement. A spring 22, compressed by a nut 24 causes the cap to fulcrum about the projection 26, and thus tends to close it. In the form shown in Fig. 4 the pin 18 is carried by the cap, and the part-spherical bush 21 engages the rounded edges 28 of an aperture in the body 11. A projection 33, Fig. 6, may be provided on the body 11 to engage a slot 34 formed in the cap 14, to ensure that the latter is lifted clear before it can be swung sideways. The sealing plate 13 is attached to the cap 14 in such manner as to permit a slight universal movement.

Title: Improvements in the manufacture of artificial filaments, ribbons and the like
IPC: D01F2/28
Filed: 1940-06-06
Abstract: 541,724. Artificial filaments, ribbons, &c. BRITISH CELANESE, Ltd., and TAYLOR, W. I. June 6, 1940, No. 9905. [Class 2 (ii)] Heavy filaments, bristles, ribbons and like articles of substantial crosssection are obtained by extruding a mass having a basis of cellulose acetate or other organic ester of cellulose and containing a relatively small amount of plasticizer, at an elevated temperature and pressure, controlling the cross-sectional area of the products by applying a steady tension as they are extruded, removing the plasticizer from the extruded products and subjecting them to saponification. Cellulose acetate, propionate, butyrate, acetate - butyrate, acetate-stearate, or other cellulose ester may be used as filament-forming substance. Products of springy character withsmooth surfaces may be obtained. The plasticizer may be used in an amount up to 30 per cent of the weight of the filament-forming substance. A small amount of a volatile solvent may be included in the composition. The plasticizer used may be triacetin, dimethyl phthalate, dimethoxy ethyl phthalate, ethyl methoxyethyl phthalate, diethyl tartrate, tricresyl phosphate, or trichlorobutyl phosphate. The products are subjected to saponification to increase their stiffness and strength. As shown, the composition to be extruded is placed in cylinder 1 provided with jacket 2 into which steam under pressure or hot oil may be introduced. The steam space may be filled with metal filings. Alternatively, the cylinder may be heated electrically. Plunger 3 presses the contents of the cylinder into die 4, the hollow interior of which leads to the jet hole 5. The face 6 of the die is recessed at 7 to protect the outlet of the hole 5 against injury. A solution of the cellulose ester composition in a solvent such as a mixture of acetone, benzene, and ethyl alcohol is worked up on malaxating rolls from which sheets of the composition still containing some volatile solvent are obtained. Discs are cut from the sheets and packed in the cylinder 1. Heat and pressure are applied to render the mass fluid and cause it to emerge through the jet 5. The filament is carried round a, feed roller 8 by means of which a steady tension is applied. Roller 8 is driven by friction wheels 10, 11, the wheel 11 being adjustable by hand-wheel 12 to enable the tension to be controlled. The plasticizer is removed by soaking the filament in a solvent such as ethyl alcohol for several hours. This treatment increases the extensibility and the product becomes more springy. The filament is then subjected to saponification with 1 per cent caustic soda solution, the extensibility being further improved. The heavy filaments may be used in the fold of leather lining-bands for hats. The Provisional Specification describes also the production of filaments having a basis of cellulose ethers, polyvinyl compounds, polyacrylic compounds, and polystyrene compounds, and is not restricted to processes which include removal of the plasticizer and saponification of the formed products.

Title: A process for the production of condensation products from trihalogen esters of fatty acids and esters of levulinic acid
IPC: C07D307/32
Filed: 1935-03-30
Abstract: Condensation products are obtained by reacting esters of trihalogen fatty acids, which are substituted in the a -position, with esters of levulinic acid in the presence of metals, especially zinc. Dehalogenation with the formation of a double linkage in the fatty acid radicle is stated to occur, and the products are lactone esters with an unsaturated side chain.  The reaction is carried out at the boiling point, preferably in dry benzene or dry ether, and the boiling is continued, e.g. for one hour, after all the zinc, which may be activated with iodine, is added.  According to examples: (1) the ethyl ester of tribromo-n-valerianate is condensed with levulinic ester to give the g -lactone of a -allyl-b -methyl-b -oxyacid adipic ester; (3) the g -lactone of a  - hexenyl - b  - methyl - b  - oxy - acid adipic ester is obtained from tribromo-n-caprylic acid ethyl ester and levulinic ester.  The g -lactone of a -pentyl-b -methyl-b -oxy-acid adipic ester may be obtained in a similar manner.
